Method and apparatus for information exchange over a web based environment

ABSTRACT

This invention discloses method and system for supporting posting (sharing) or un-posting (stop sharing) files, folders, and messages through utilizing private and group common workspaces. The stop sharing file or folder will not delete actual file or folder that contradicted to and enhanced for the then-existed technology for the file and folder sharing. The un-post message operation facilitates a user to remove (delete or withdraw or stop sharing) his/her previously posted message from viewing of a recipient such as from a user interface (UI) of the recipient, so that the user can avoid embarrassment if the message was not proper. Thus, the un-post the posted message has also enhanced the then-existing technology with better user experiences for message sharing.

FIELD OF THE INVENTION

The present invention generally relates to communication network. More specifically, the present invention relates to web based communication system.

BACKGROUND OF THE INVENTION

With increasing popularity of using the Internet and World Wide Web (“the Web”) for the rapidly changing digital world, individuals as well as enterprises exchange (or swap) large volumes of information through the Web. The demand for larger and faster information exchange has increasingly grown in recent years. For example, various business meetings and conferences are conducted over the Web with attendees scattered around the world. To enhance the communication between the meeting attendees, not only voice (and/or image) information is important, but also information exchange can be critical.

Fast, volumes, and secure information exchange is important in enhancing the efficiency of a communication network. A problem associated with a conventional network is limited size and speed. For example, a typical email system limits the size of each email, such as 10 megabytes, thereby a reasonable speed of delivery of such email can be achieved. Another problem associated with a conventional network is that various hosts require specific software installation before a user can use their platform. For example, Skype™ requires users to install its proprietary software on the user's systems before it allows them to use its platform.

Accordingly, there is a need in the art to provide faster, more secure, and volume information exchange over the Web.

SUMMARY OF THE INVENTION

The present invention relates to a method and apparatus for information exchange over a web environment.

With the development of central controlled distributed scalable virtual machine (CCDSVM) and the web-based computer user working (operating) environment (WCUWE), the problems mentioned in the previous section can easily be solved by introducing a “dynamic work space” technology of this invention within the frameworks of the CCDSVM and the WCUWE.

With dynamic work space technology, one or more login users of the CCDSVM, each using a browser of any system and from anywhere, can instantly perform tasks. For example, each user can post or un-post messages, files, folders, or other resources on systems of the CCDSVM, with group-based model or non-group 1-to-1 model, to one or more other users on said network. This technology will also achieve larger scales of secure information exchange without size limitation and the installation of special software.

The implementation of this invention has provided users with a web browser based, 1-click system that is capable of securing exchanges of messages, files, folders, or other information resources on systems crossing network domains without size limitation.

Additional features and benefits of the present invention will become apparent from the detailed description, figures, and claims set forth below.

Therefore, the appended claims are intended to encompass within their scope all such modifications as are within the spirit and scope of this invention.

The present invention can be implemented by a web based system operated in a network infrastructure, such as a central controlled distributed scalable virtual machine (“CCDSVM”). FIG. 1 illustrates a CCDSVM in accordance with an embodiment of the present invention. The CCDSVM includes a group of provisioned systems 3, a control management system 2, console systems 1, and client systems 10. The control management system (“control system”) 2 is configured to control a group of systems (“provisioned system”) 3. The console systems (“console systems”) 2 provides management while client systems 10 (“client systems”) initiate accessing the provisioned systems 3 via a web-browser over a network infrastructure, such as a corporate Intranet, the Internet, and/or a LAN.

The network infrastructure (“network”) includes all necessary hardware and software that facilitate various users from different geographic locations to communicate through the Internet, an Intranet, and/or a LAN. The hardware of the network includes network connection media, wireless media, circuitry components, and communication equipment. The network connection media includes various cables such as Ethernet and/or optical fiber. The wireless media are capable of establishing wireless communication links through air. The circuitry components include processor, data bus, memory devices, and/or circuit board. The communication equipment, such as switches, routers, gateways, and/or adapters, are used to provide a communications network. It should be noted that there are other possible elements of communication equipment that may be needed to form a communication link, but they are not necessary to understand the present invention.

The software infrastructure includes Internet Protocol (“IP”) addresses and system name identification software such as Domain Name Server (“DNS”), firewall software, IP gateway set-up software, IP broadcast. The communication protocols over the network could be IP-based standard or non-standard proprietary protocols such as Hypertext Transfer Protocol (“HTTP”) over Transmission Control Protocol/Internet Protocol (“TCP/IP”) or Simple Object Access Protocol (“SOAP”) over TCP/IP. It should be further noted that some of the IP based protocols are proprietary protocols and some of them are non-IP based protocols.

A web-browser is an application program that allows a user to access information over the Web, such as Windows Internet Explorer (“IE”), FireFox, Netscape, and/or Mozillar. A web-browser could also be proprietary software, which uses web-protocols such as HTTP, WAP, SOAP for communication over the network. The web-browser can be implemented with suitable programming languages such as C, C++, Java, or XML, or a combination of the suitable languages.

A web page, on the other hand, is encoded for displaying information and is accessible through web-browser. The web page may be hosted by a web server via a web server system and can be transmitted (or retrieved) by a web-browser.

The provisioned systems 3, client systems 10, console systems 1, and control management system 2 are computational systems, which could be server system, desktop or laptop system, handheld devices such as PDA, wireless phone, and so forth. The computational system includes CPUs, storage devices, and memory controller. The storage devices include internal memory such as read-only memory (“ROM”) and/or random access memory (“RAM”). The storage devices may further include external storage devices such as magnetic disks or tapes drives, include redundant array of inexpensive disk drives (“RAID”), just bunch of disk drive (“JBOD”), and memory stick. The associated storage controller can be Integrated Drive Electronics (“IDE”), Small Computer System Interface (“SCSI”), Fiber optical controller, or a combination of above-mentioned devices.

The computational systems also include non-embedded or real-time embedded operating system (“OS”), which could be Linux, or Windows, Unix, or proprietary OS. It should be noted that the present invention may include multiple control systems at different layers of a system configuration topology, where each of the control systems is capable of communicating with each other through a network. The control systems at middle layers play dual roles as both control system and provisioned system in the system configuration topology.

FIG. 1 illustrates a CCDSVM platform with multiple clients 10 in accordance with one embodiment of the present invention. The CCDSVM includes the console systems 1, a control management system 2, the provisioned systems 3, and networks 11-12, wherein networks 11-12 are used inter-connecting with all systems of the CCDSVM and the client systems 10.

The console system 1 is a computational system having a web-browser or (web-console) 9 wherein the web-browser is used by privileged users for accessing the CCDSVM platform. The web browser 9, which could be on a computing system, permits a user to access information of the CCDSVM by following a web URL link. For example, a privileged user enters a URL of “https://69.107.28.123/stt/sttwebos” on a command line of the web browser 9 and once the link is established, the user can obtain information hosted by the web-based computer user work/operation environment (“WCUWE”). The console system 1, in one embodiment, further includes software modules 13, where the software modules 13 may be used to facilitate communication between the console system 1 and the control management system 2.

The control system 2, in one embodiment, is a server system, a desktop or a laptop system with the memory and storage capabilities. The control system 2 includes web server software 7 and console supporting software 6. The console supporting software 6 includes web server interface software modules 5 and control management software modules 4. The control management system 2 may also have a web-browser 9 used as a web-console 9 of the control system 2. The web server software 7 sends/receives data to/from the web-console 9 of the console system 1 or the client system 10 or the control system 2. The web server software 7 is configured to provide secure sockets layer (“SSL”) encryption to encrypting the data before transmission to enhance the security. The web server software 7 could be commercially available software such as Apache™ from open source, or IIS from Microsoft or a proprietary software. The web server software modules 7 and console support software modules 6 can be implemented by suitable or a combination of suitable programming languages such as C, C++, Java, JavaScript, HTML, or XML.

The console supporting software 6 communicates with the service software modules 8 of the provisioned systems 3. The web server interface 5 of the console support software 6 is capable of providing special functions that are otherwise performed by the web server 7. If there is no provisioned system 3 coupled to the CCDSVM platform, the control management system 2, in one embodiment, is reconfigured to continue monitoring systems over the network while the CCDSVM platform is also reconfigured into a single stand-alone system, as shown in FIG. 2B. Therefore, users can access and/or obtain resource objects or system resources via the web-browser 9, which can be resided on client system 3 or console system 1.

The provisioned system 3, in one embodiment, is a computational system containing suitable operating system (“OS”). The provisioned systems 3 can be automatically provisioned by the control system 2 through an automatic system service pool construction protocol. Provision process, also known as pooling process, is a method allowing the control system 2 to control one or more network systems by reconfiguring the network systems. For example, when a provisioned system boots up via said communication protocol, the control system 2 automatically obtains provisioned system's name, IP address, and system information, where the system information includes network information, storage information, file system information and so forth. Thus, each provisioned system 3 can be monitored, accessed, and/or operated by a user(s) through the web-browser 9 on the console system 1. In an alternative embodiment, provisional system 3 is controlled by users through client systems 10 via the control system 2 with proper users' authentication. Each provisioned system 3 contains service software modules 8, which is used to communicate with servers over the Web. For example, the service software modules 8 of provisioned system 3 can communicate with the control management software 4 of the control system 2 to carry out tasks received therefrom for viewing or operating resources of the provisioned system 3. The service software 8 can communicate with the web-browser 9 of the client system 10 or console system 1 to transfer data between them or deliver service to them, or to communicate with another provisioned system 3 to send or receive data.

The service software modules 8 may include special software modules having compatible functionalities as the web-server software 7 of the control system 2 has for dedicatedly handling HTTP protocol or other web protocols for web-based communication with the client 10 or with the other provisioned systems 3 or with the control system 2. The software modules 8 could be commercially available web server software 7 or proprietary software. The service software modules 8 could be implemented with suitable programming languages such as C, C++, Java, or JavaScript.

Net 11 and Net 12 are network infrastructures that are capable of providing communication links between the control management system 2, console systems 1, client systems 10, and/or provisioned systems 3.

The client systems 10 may not be a part of the CCDSVM, but with the permission and authorization, a user from the web-browser 9 of the client system 10 can login to the CCDSVM and access the permitted resources of the CCDSVM by following a web URL link of the CCDSVM. While the privileged users can obtain, manage, access, and/or operate system resources of the CCDSVM through the WCUWE, regular (non-privileged) users at the client systems 10 may be permitted to access only limited system resources of the CCDSVM.

The CCDSVM configuration, in one embodiment, includes four data flow paths. First data path is a communication link between the web browser 9 of the client host 10 (or console host 1 or control management system 2) and the web handling software on the control system 2 (such as web-server 7 or console support software 6). With this path of data flow, whenever a user sends a request from the web-browser 9 to the web-server 7 or the console support software 6, the console support software 6 collects required information from target provisioned systems 3 and converts the information into standard structured information (web-format) for web communication. The targeted system could be one of the provisioned systems 3 or the control system 2. The information collected by the console support software 6 of the control system 2 could be the system status, or the storage information, or the network information, or the user authentication profile, or the file system information, or files & folders information on the control system 2, or on the a targeted provisioned system 3. The console support software 6 then passes this converted structured information to web server software 7 and further sends it to the web-browser 9 through a communication link of the Net 11 and Net 12 so that it can be displayed and viewed by the conventional web browser 9, as shown in FIG. 1.

The communication protocol used between the web-browser 9 of the client system 10 (or the console system 1 or the control system 2) and the web server 7 of the control system 2 could be HTTP, HTTPS (SSL encrypted HTTP protocol) or suitable web protocols for web communication, which could successfully transmit the data across the web or could be other standard or proprietary IP-based on non-IP-based protocols. This data path may be referred to as the console support software 6 transmits data to or receives data from the web-browser 9 or web-server 7.

The second data path is the data flow through communication links between the control system 2 and provisioned systems 3. Requests targeted to a provisioned system 3 are passed from the console support software 6 of the control system 2 to the service modules 8 of the provisioned systems 3 through communication link network 12. When the responses for those requests are received from the control system 2, the service modules 8 of the provisioned system 3 carry out the requested tasks, and then send the response back to the console support software 6 of the control system 2. The implementation of the actual products of this invention for the second data path may use proprietary TCP/UDP/IP based protocols for the communication between the provisioned systems 3 and the control system 2. However, other standards or proprietary IP-based or suitable non-IP-based protocol are also possible. The communication protocols used between the console support software 6 of the control system 2 and the service modules 8 of the provisioned system 3 can be suitable IP based or non-IP based protocols, whichever is suitable to transmit data between them. The typical data flow through this path could be the boot message, system status, network information, or storage information of the provisioned system 3 as shown in FIG. 1.

The third data path is the data flow between the provisioned systems 3 and the client system 10 or the console system 1 via the communication links of the net 11-12. Referring back to FIG. 1, the console support software 6 of the control system 2 may present a web link, which points to an object on a provisioned system 3, to a user working via a web-browser 9 on the client system 10 or the console system 1 or the control system 2. The object pointed by the web link on the provisioned system 3 could be a text file, MPEG video, PDF document, MS Power Point, Word documentation and others. It also could be a link of another web service program. From the web browser 9, a user can directly access the information on a provisioned system 3 pointed by the web link without go through the control system 2 again. In this case, the service modules 8 of the provisioned system 3 also include web server software modules 7 or equivalent one to directly support the web browser 9 as mentioned before. The communication protocols with the third path could be web protocols such as HTTP or WAP. Alternatively, the communication protocols can be other standards or proprietary IP-based or non-IP-based protocols. To simplify the discussion, the data transmitted on this path will be mentioned as the service software module 8 that send data to or receive data from the web-browser 9 and/or vice versa.

The fourth data path is data flow through communication link between a provisioned system 3 and another provisioned system 3. With this path, the service modules 8 of one provisioned system 3 can directly transmit data or information to the service modules 8 of another provisioned system 3 via a communication link of the Net 12 without going through the control system 2. The implementation of the actual products of this invention, for example, uses a proprietary IP-based protocol for communications between the two provisioned systems 3. The principle of this invention, however, does not rely on or limit to proprietary protocol. It should be noted that other standard or proprietary IP-based or suitable non-IP-based protocol may also be possible. The data and information transmitted through the fourth data path can be various types of data. For example, a user at a web-browser 9 may open a file folder on a provisioned system 3. The user can also instruct to transfer a file from a current target provisioned system 3 to another provisioned system 3 by a mouse click. The data file will then be transferred directly between the two provisioned systems 3 without going through the control system 2.

FIG. 2A illustrates a variation of the CCDSVM platform for the web browser-based communication in accordance with one embodiment of the present invention. The CCDSVM platform illustrated in FIG. 2A is similar to the platform illustrated in FIG. 1 except each of provisioned systems 3 includes a web-browser 9. Thus, with proper authentication process, each user of provisioned systems 3 may access, manage their own provisioned system 3 from the web-browser 9 either on their own local provisioned system 3 or on client system anywhere on the network. It should be noted that when a user is registered with a provisioned system 3, the user is authorized to access provisioned system 3 locally but not with the CCDSVM. On the other hand, when a user is registered with CCDSVM, the user is then authorized to access the multiple provisioned systems 3 and the control system 2 of the CCSDVM.

FIG. 2B illustrates another example of a variation of CCDSVM, in which there is no provisioned systems 3 in the CCDSVM. The Control system 2 can run on its own and the CCDSVM has degenerated into a single stand-alone system (FIG. 2B), and users through web-browser 9 on client system 3 (or on console system 1, or on stand-alone control system 2) are allowed to access and operate the permitted resource objects and system resources on the stand-alone control system 2.

Unless specifically specified, the console support software modules 6 of the control system 2, the provisioned systems 3, the service software modules 8 of provisioned system 3, and the web-browser 9 on the control system 2, the client system 10, and the console system 1 are referred to the CCDSVM platform illustrated in FIG. 1.

A web-based computer user work/operation environment (“WCUWE”) of CCDSVM is a software infrastructure, shown in FIG. 3, which provides each permitted user to log into CCDSVM and further provide each user a private web-browser based operating environment, which is a private work space including the assigned and permitted resources on the control system 2 or on the provisioned system 3 across the network. The WCUWE further provides each user from a single web-browser to perform various permitted tasks and operations over various system resources (FIG. 5), further, the tasks can be performed concurrently from a single web-browser.

The tasks include allowing privileged users to create users, and user groups, assign users to each group, to assign initial associated system resources to each user or group, and to save the information of created users and groups into a database stored on storage media of the control system 2. The information needed for creating users or groups include user names, user IDs, assigned security permissions, passwords, access points, group names, group IDs, maximum members in a group, and so forth. The tasks also include various system operations such as manage network, storage, file system, folder, files, messages, user security, and so forth.

The database is organized as one or more lists of tables, wherein each of the lists contains information for various resources. The resources could be one or multiple users' information, one or multiple systems' information, one or more network cards, and one or more disk drives information. The storage media could be a system's internal storage or disk drive, for example.

The WCUWE of the CCDSVM includes software modules of present invention. For example, the software includes the console support modules 6 of the control system 2, the service software modules 8 of the provisioned system 3, the other service software 13 of the console system 1. The current implementation of the WCUWE is based on a proprietary design of this invention. However, the nature and spirit of this invention does not limit to proprietary designed software. The WCUWE of the CCDSVM also includes other proprietary software modules or conventional software such as the web-server 7 of the control system 2, the web-browser 9 of the control system 2, the client system 10, and console system 1.

The WCUWE of the CCDSVM can be implemented with suitable or combination of various suitable programming languages such C, C++, Java, JavaScripts, HTML, WL, and so on. To simplify the discussion, the WCUWE will be used to represent software modules in the CCDSVM described above.

Users of the CCDSVM may be created by the CCDSVM though a given process or users are on the Internet, Intranet, LAN without registering with CCDSVM. The WCUWE of the CCDSVM provides user to access various resources and perform various tasks through a preferred model of mouse clicking graphically represented resource objects displayed on the browser 9.

The WCUWE is designed to be operated on a CCDSVM platform, and specially is designed to provide dynamic work space (FIG. 4A) to each user associated with the various CCDSVM. The WCUWE further facilitates each user performs tasks of instantly posting or un-posting user's private resources information to peers in a group or to each peer user of the CCDSVM not in a group or not in a same group, or to massive public users on the network, where the massive public users do not have accounts with the CCDSVM platform.

The dynamic work space of the WCUWE is a centrally controlled collection of each group's work space and/or user's work private space. The console support software 6 of the control system 2 of the CCDSVM will assign each user a private work space and each group a common work space when each user or group account is created by a privileged user after corresponding WCUWE software modules on the control system 2 and provisioned system 3 enter into an operational mode. When a user or a group account is created, each user is assigned with a specific user security scope and permission. An important aspect of the WCUWE of the CCDSVM is that it assigns each user and/or each user-group a working space based on user and group security permission.

A work space is an organized information structure, which can be saved on storage media of memory or disk drives or both of memory and disk drives by the console support software 6. A work space is created during a privileged user performing the tasks of creating user or group. The work space will be initiated and assigned with system resources of the CCDSVM as shown in FIG. 5. Various system resources on either the provisioned system 3 and/or on the control system 2 include respective memory, system-groups, computing systems in a system-group, file system, file folders, files, storage media, network media and so on. The common work space 15, shown in FIG. 4A and FIG. 4B, of each group may be initially assigned with information of system resources (FIG. 5) such as users in this group, message area, file systems, folders and files on a specific provisioned system 3 or on the control system 2, and so on. The resources of the common work space may also be dynamically assigned or allocated by permitted user after creating group account. For example, during an online interactive meeting, a user posts a file to the common work space, so that a new entry of a file node is added to a file and folder tree area of common work space. In addition, each group may be assigned with one or multiple users, wherein each user can also be assigned with a private work space 16 illustrated in FIG. 4A and FIG. 4C during user account creation time. The private work space may also be initially assigned with system resources of the CCDSVM during user account creation time. Alternatively, the private work space is dynamically assigned with the resources of the CCDSVM after the user account being created.

For example, a privileged user can dynamically permit or deny a general user to access a list of storage devices. During the operation, at one second, the user may see the list from the user's web-browser, and at another second, the general user will no longer see the list. Also, if the authorized user can access to the list of the storage devices on a provisioned system 3, and further can take one of the devices offline so that the device list on the provisioned system 3 will have one less device to be displayed.

In another example, at one second, a privileged user allows a general user to access a file J in a folder N on a system M of the CCDSVM, and at another second, the privileged user resets the previous permission, thereby, the general user can view and access the file J in the folder N of the system M of the CCDSVM at one time, and a second later, the general user can not view and access the file J any more. The actual implementation of console support software 6 of control system 2 has achieved this capability.

In addition, each type of resources in the work space is organized as a list of tables and can be stored in storage media in the control system 2. The integrity of security of each group is protected by limiting different resources to different group. As such, each group is authorized to have a limited view over assigned system resources on the provisioned system 3 as well as on the control system 2. The same security integrity at user level can be achieved by assigning different system resources of the provisioned system 3 and/or the control system 2 to different individual user based on assigned security permission. Therefore, each user is authorized to access and view the assigned resources only.

FIG. 4B has shown an example of assigned resources of users 17, message area 18, folders and files area 19, and other areas 20 in the common work space 15 of a group. The messages, from each user in the user group, in the common message area 18, and the information of folders and files in common files and folder area 19 can be shared by all users in the same user group. All resources in each group's common work space can be selectively displayed in the web-browser 9 of each login user, who belongs to the same user group after said resources in said group being converted to presentable web-format (web-page) by the console support software 6 of the control system 2 of a CCDSVM.

FIG. 4C has shown an example of resources in private work space (16) of a user, which has assigned private message area 21, private file, folder area 22, and private network or storage or other information areas 23. The assigned resources in the private workspace only can be exclusively viewed and accessed by the designated user unless he/she agrees to share with peer user crossing group boundary or with peer users in a same group. The folder (directory) is a data structure which can hold one more files and sub-folders at logical file system level and at physical level on storage media.

FIG. 8A has shown an example of displaying an actually implemented portion of web-page encoded with assigned resources in private work space of a user X, which includes a system-group-A 33 on said network, multiple provisioned systems 3 under the system-group-A, private folders 32 and 34 of the user X on a system, and files under the folders 32 in the displayed private work space of the user X.

FIG. 8B has shown another example of displaying an actually implemented portion of a web-page encoded with assigned resources in a private work space of a user Y, which includes a control system 2, private folder and files 35 of the user Y in the displayed private work space of user Y.

The private work space of the user X and user Y may also include private message area 21 and other resources, which are not displayed in FIG. 8A & FIG. 8B because the WCUWE is designed to dynamically display part of user's private work space whenever there is needs.

It is notable that said user X and user Y, may be in same user-group such as in said group-1, however, each of them could have a significant different scope of the private work space assigned by the console support software 6 of the control system 2. This is due to they have been assigned with very different resources on the systems depending on each user's role and security permission, which is setup by privileged user of the CCDSVM through web-based user interface provided by the console support software 6. This is the beauty of the invention of WCUWE for CCDSVM.

The FIG. 6C and FIG. 6D are examples of a web-page displayed in said web-browser 9 for each of the user X and user Y in the user group-1 before an interactive online meeting. As shown in FIG. 6C and FIG. 6D, the user X or user Y or other users (who's web-page/browser were not depicted) in the same user group-1 have entered a group online meeting after their login to the CCDSVM from each browser 9 on a computing system on said network. All users get an identical web-page provided by the console support software 6 of the control system 2 except with different contents in the displayed private work space section of the web-page due to each user has assigned with different resources. The web-page screen layout provided by the console support software 6 contains four sections:

-   -   1) a private user message input area (section-1),     -   2) a message displaying section for displaying common message         area 18 shown in FIG. 4B for all users in a user group-1         (section-2),     -   3) a file or folder display section for displaying group common         file and folder area 19 shown in FIG. 4B for all users in same         user group-1 (section-3), and     -   4) a file and folder tree displaying and management section         (section-4) for displaying user folder and file tree in private         file and folder area 22 as shown in FIG. 4C, of a user's private         work space 16.

Initially, the section-1, section-2, and section-3 are all empty due to no one has posted any file or message yet. The console support software 6 gets each login user's portion of assigned folders and files for the online meeting from the stored private file and folder area 22 of the private work space 16 of each user on said storage media, and further converts said file or folder information to presentable web-format (web-page) to be displayable in said section-4 of the web-page in web-browser 9 of each user. The choice of total four sections of the web-page layout and the order of each section on the browser screen 9 is irrelevant to this invention since other choices of designing are also possible, and further, this invention does not have limitation on what web-screen layout shall be. The information of the file or folder includes the system name where the file or folder resided, the name and path of the file or folder, the owner of file or folder, the time stamps, the size of the file and so on without limitation.

During the interactive online meeting, the console support software 6 provides each user to post or un-post files or folders to said section-3 of displayed group's common documents and contents management section with several steps. First, for example, providing said user X to click on one targeted file “Doc 1” 24 or “sub folder-1” in the section-4 of the displayed file and folder management area of said user X's private work space 16. Second, select the operation of either post or un-post from an operation menu (see FIG. 9A, FIG. 9B, FIG. 10A and FIG. 10B). Finally click on the selected operation to submit the task of either post or un-post the selected file or folder.

Each user with permission may perform un-post operation if such user has at least a previously posted file or folder, which has already displayed in section-3 of the common document and content management section of said web-browser 9, see FIG. 6A or FIG. 6B for example.

If a file is selected, the file operation menu is used and if a folder is selected, the folder operation menu is used respectively. It is also possible to only provide one menu for both file and folder operation by the console support software 6. The operation menu either can be pop-up menu for folder as shown in FIG. 9A or pop-up menu for file as shown in FIG. 9B, or non-pop-up menu for folder as shown in FIG. 10A or non-pop-up menu for file as shown in FIG. 10B. The choice of operation menu is irrelevant to this invention although the actual implementation of this part of invention has used pop-up menu, and as matter of the facts that there is no limitation on how the operation menu is to be designed in this invention.

In the example of FIG. 6A, the user X can post a file named “Doc 1” 24 to said section-3 of the common document and contents display section in said web-browser 9, In the example of FIG. 6B, the user Y also can post a file named “picture 1” 25 to the common document and contents display section in said web-browser 9. In addition, another not depicted user Z posted a file of “project code”. The files or folders could be one on said control system 2 or on a provisioned system 3 of the CCDSVM.

In addition, during the interactive online meeting, the console support software 6 of the control system 2 also provides each user to post message to other users in same group from said section-1 of the private user message input section after typing a message and click on the “send” button. In the example of FIG. 6A, the user X posted a message of “Msg1 of user X” 26. In the example of FIG. 6B, the user Y also posted a message of “Msg2 of user Y” 27. In addition, another non depicted user Z posted a message of “Msg3 of user Z”. As a result, all of three messages were displayed in the same section-2 of each user's browser.

In a specific situation, the console support software 6 also provides permitted user to un-post the previously posted message. Just for example, in FIG. 6A, the console support software 6 provides the permitted user X to select a previously posted “Msg2 of the user Y” 27 from said section-2 of the common message display section of said web-browser 9 of the user X, and select un-post operation from said operation menu and submit the selected un-post task.

The detailed information of how the post or un-post task to be implemented will be discussed in next two paragraphs. In addition, with this invention, the action of the “post” information such as posting information of files or folders or messages or other resources is equivalent to the action of “share” the information. The action of “un-post” information is equivalent to the action of “un-share” a previously posted or shared information, in other words, to “remove” the previously posted or shared information.

After transmitting information of the post or un-post task from the web-browser 9 of the console system 1 or client system 10 or control system 2 to the control system 2, the console support software 6 of the control system 2 obtains and parses the received data to determine: who is the original user initiating the task; what type of task; what type of associated resources for task to work on; who is the targeted user; and what is the time stamp, and may also include other information without limitation. The console support software 6 further determines that if the task is to post a file or folder from the original user, the console support software 6 picks up the corresponding file or folder information that from file and folder area 22 of the private work space 16 of the original user, and deposits such information to the file and folder area 19 of the common work space of said group 15 in this case.

If the task is to un-post a previously posted file or folder, from a specific user, in said common work space 15 of said group, the console support software 6 search for the corresponding information of the file or folder in the file folder area of said common work space 15 of said group and further remove the entry of matched information from said common work space of said group after it is found.

If the task is to post a message to users in said group, the parsed message will be stored in the private message area 21, of the original user's said private work space 16, and also is copied to the message area 18, of the common work space 15, of said group by the console support software 6.

If a task is to un-post (delete/remove) a previously posted message, the console support software 6 searches for a matching message in said common message area 18, of said common work space of said group, and remove such message entry if it is found based on the message and original user's identification and other associated information such as time stamp, security permission and so on without limitation.

It shall be noticed that the task of un-posting a file or folder of this invention does not actually delete the file and folder from original user's private work space. In addition, a lock protection mechanism is deployed whenever a message or information of a file or folder is written, stored, or deposited to either said private work space or said common work space, or to said disk drives or other storage media. Throughout the rest of discuss, the lock protection is assumed to be a default action without further mentioning whenever a write/store/deposit action take place. As matter the fact, each task of posting file, folder, and message as well as the task of un-posting the previously posted file or folder, or message performed by multiple users in multiple groups with this invention can be executed by the console support software 6 instantly with memory speed.

FIG. 6A and FIG. 6B illustrate that after the console support software 6 of the control system 2 successfully executing the tasks for each user in each group, each user in said user group can get a fresh view of said section-2 of the common messages display area of the user group-1, and a fresh view of said section-3 of the common documents & contents display area in each user's said web browser 9 on the client system 10 or on the control system 2 or on the console system 1.

User can manually click on a refresh-button, which does not show on the FIG. 6A and FIG. 6B, to refresh corresponding part of screen of either said section-2 or section-3 in the browser 9. As a result, said corresponding part of browser screen of said section-2 or section-3 can be automatically refreshed. As mater of the fact, optionally, the console support software 6 has encoded a run-time script in a web-page, which is encoded with said presentable web-format for being displayed in said web-browser 9 after each user login to the CCDSVM and started group online meeting.

The run-time script will automatically and periodically perform/submit tasks of refreshing said section-2 and section-3 of the web browser 9 screen. The frequency of the periodic refreshing can be adjusted by said console support software 6 of the CCDSVM depending on the needs of the meeting, which typically can range from 1 to 3 seconds and there is no limitation on this aspect. Also, with the preferred example, the run-time script provided by the WCUWE is a JavaScript, however, other type of programming scripts or methods are also possible and there is no limitation on what kind of run-time program shall be used in this invention. In addition, the console support software 6 provides each user the choices of either automatic or manual refreshing their web-browser 9.

Upon refreshing said section-2 or section-3 of said web-browser 9's screen, a request of updating such screen will be generated and sent from said web-browser 9 to the control system 2. The console support software 6 obtains and parses each request to determine what user group, and which part of said common work space of said group need to be updated.

Based on information of each parsed request, the console support software 6 of the control system 2 retrieves the updated resources and objectives from said common work space 15 of said user group, which includes recently posted files, folders, or messages from each user in said group, and also includes the updated list of files and folders or messages after un-posting one or more files or folders, or messages by the users in the same group. Finally, the console support software 6 of the control system 2 converts retrieved information of the resources and objects to the presentable web-format (web-page).

If the request is to update the group messages, the converted information is sent to the section-2 of the group common message display area in corresponding user's web-page/web browser 9. If the request is to update the group common files and folders display area, the converted information is sent to the section-3 of said web-browser 9. Therefore, after refreshing said sections on the web-browser 9, each user can have an identical view of all posted files and folders in the section-3 of group common document display area on said browser 9, and can have an identical view of all messages in the section-2 of the group common message display area on said web-browser 9, which are posted by all other users in a same group. Meanwhile said console support software 6 still allow each user kept most of the resources and objects in their own private work space un-exposed to other users in the same group during the online interactive meeting.

For example, the User X at his/her web-browser 9 can see “picture 1” 25, posted by the user Y, in the group common file and folder display area but cannot see other information in the user Y's private work space area, and can see the “Doc 1” 24 posted by the user X himself. Also, the user Y at his/her web-browser 9 can see “Doc 1” 24, posted by the user X, in the group common file and folder display area but cannot see other information in user X's private file and folder display area, and can see the “picture 1” posted by the user Y himself.

A difference between a conventional Internet group communication model and the group based communication model described in the present invention is that the console support software 6 of the control system 2 provides each user to control post or un-post said resources from user's own displayed private work space while the conventional Internet communication model are not capable of performing such posting/un-posting task. For example, un-posting a previous posted file or folder with the WCUWE of the CCDSVM does not delete the materials of the file or folder in the user's private work space while the delete operation with existing Internet group communication model will completely delete the file or folder. The dynamic work space of this invention has combined with security protection for the information and, flexibility and efficiency for online meeting provided by the WCUWE of the CCDSVM to each of user and groups.

In addition, with a preferred example, posted information of each file is encoded by said console support software 6 with a web link and displayed in said section-3 of the web-browser 9. Therefore, each user in a user-group can click on said link to download the file, which provided in the private file and folder area 22 of the private work space 16 of peer user, from a system where the file is located. For example, the user X can download said “picture 1”, which may reside on either a control system 2 or provisioned systems 3, from the user Y, while the user Y can download said “Doc 1”, which also may reside on either a control system 2 or provisioned system 3, from the user X at same time. This achieves a true peer-to-peer exchanging files on permitted system from permitted users in said user group. In addition, there is no limitation on the file size of the file to be downloaded, which is a gifted benefit from Internet technology. Besides the exampled and understandable method of download, other methods of retrieve peer users' digital documents or contents are also possible by deploying a more efficient proprietary file transfer mechanism to reach the results of said exchanging file. It shall be noted that the method of download is only applicable to the files and does not apply to folder and other resource information. To get a targeted peer user's entire folder and the underneath files and sub folders, a special files and folder transfer method is required.

As shown in FIGS. 9A & 9B, and FIGS. 10A & 10B, the console support software 6 of the control system 2 also provides each user to perform many other tasks during online meeting through said operation menu such as upload, rename, delete, copy/paste and so on without limitation. The upload operation allows each user to dynamically upload files one a time through the web-browser 9 from a local storage of the client system 10 or console system 1 to said user's private work space on the control system 2 during the meeting, and further to be posted to said common space of a user group that each user belong to.

The mouse click driven copy/past operation allows files and folders from permitted folders of permitted provisioned systems 3 to be dynamically physically copied to each users' private work spaces 16 on the control system 2, and the information of said files and folders could further to be displayed via said web-page in the browser 9 of each user and to be further posted to the common work space 15 of said group which each user belong to in addition to the direct posting these file or folders as described previously—without physical copying over. As matter of the fact, operations provided by the console support software 6 of the control system 2 have added efficiency to posting or un-posting files and folders for each user depending on the real needs.

Additionally, said console support software 6 provides each user of each group capability of saving the posted messages in the common message area 18 of said common work space 15 of each group as a file in the common file & folder area of said common work space 15 of each group. Further, the saved file can be viewed, downloaded by each user in each group with same method of posting. Besides whenever there is a need, said console support software 6 provides users to reset message area to be empty by removing all message entries in the message area 18 of said user group's common work space 15.

An important fact is that the designed WCUWE of the CCDSVM has provided concurrent users each from a single web browser anywhere on the network to securely perform permitted various tasks, which could be run concurrently within a single web-browser. Because of the console support software 6 of the control system 2 let each users have exclusive view for resource objects in his/her private work space 16 and in said common work space 15 of a group which each user belong to and let each user to manage resource objects in his/her own private space, the multiple users in multiple user groups can concurrently post or un-post files, folders, messages, or other resource objects without interfere users in other user-groups. Thus, the work spaces of each user and each group are well protected.

Hence, the console support software 6 of the control system 2 provides privileged users to perform tasks of creating multiple users and user groups on the control system, and each group can be assigned with variable size of the users for online interactive meeting. The total number of users and the total number of groups, and maximum number of the users per groups of the WCUWE of the CCDSVM can support is an implementation issue and depends on the capacity of the control system 2. The WCUWE of CCDSVM and the CCDSVM has been designed with unlimited scalability for both users and provisioned systems 3. On the other hand, the spirit of this invention does not limit to with the boundary issues of the WCUWE and the CCDSVM.

FIG. 8A and FIG. 8B illustrate that each user X and user Y has a different private work space 18 than others, and each has assigned with different system resources. Without joining a group or participating a group meeting, the console support software 6 of the control system 2 also can provide user X and user Y to peer-to-peer instantly posting files or folders one a time to each other, or instantly un-post the previous posted files and folders through similar steps as posting or un-posting materials in group online meeting model:

-   -   1) Let each user select, via mouse clicking, a source of file or         folder for post or un-post;     -   2) Let the user to select a post operation (task) if the user         wants to post a file or folder through an operation menu; or to         select an un-post operation (task) from an operation menu if         said user like to un-post a previously posted file or folder;     -   3) upon submitting the operation (task), let each user provide         input to a prompt of “who is a targeted user?” which provided by         said console support software 9, and further submit the selected         task;     -   4) Said console support software 6 obtains and parses the task         information of original user, source of the file or folder, type         of operation, and other information;     -   5) If said type of the operation is post file or folder, said         console support software 6 deposits the information of said         source file or folder to said private file and folder area 22 of         said private work space 16 of a targeted user. If said operation         type is un-post a file or folder, said console support software         6 searches a corresponding file or folder information from said         private file and folder area 22 of said private work space 16 of         said targeted user to match the source file or folder, if found         a match, the corresponding entry of the file or folder is         removed from said private file and folder area 22 of said         private work space 16 of the targeted user; and     -   6) Upon each user refreshing the web-page in web-browser 9, the         console support software 6 retrieves and converts the updated         information in said private file and folder area 22 of own         private work space 16 of the user into a presentable web-format         (web-page) and transmits said web-page to the web-browser 9 of         the user for displaying and viewing.

For example, as shown in FIG. 8A, the user X can follow said steps 1) to 3) to post his “folder 2” 32, in the displayed files and folders area 22 of private working space 16 in the user X's web-browser 9, to the user Y. As shown in FIG. 8C, upon the user Y refreshing his/her web-browser 9 on a system by walking on a corresponding system node or folder node in the displayed tree, the user Y will see the “folder 2” 32 in his/her displayed private file and folder tree in the displayed private work space of user Y shown in FIG. 8C. As matter of the fact, when walking a system node and/or a file & folder tree in said web-browser 9, a refreshing web-page screen request is generated and to be handled as described previously.

In addition to post or un-posting messages in the group based communication involving parties with two or more users, the WCUWE of the CCDSVM also provides each user to post message to each other user with non-group based 1-to-1 message model. FIG. 7A and FIG. 7B have shown an example of a user X and a user Y, who may not be in a same user group, however, the console support software 6 of the control system 2 provides each user to share and exchange messages with each other from a three-section web-page in said browser 9.

The section-3 of the web page in said browser 9 let user to work with same said steps of non-group based 1-to-1 posting files and folders or un-posting the previously posted files or folders as described in prior paragraphs—The section-3 included in FIGS. 7A and 7B just for a demonstration of how flexible of this invention is to display information under private work space of each user. Further, the number of sections in the screen layout and the order of each section in web-page display really is not a limitation to this invention.

The section-1 is a user message input area together with an additional input field of “To who” due to unlike in group online meeting, the console support software 9 have no knowledge of who is the targeted user in this case. Thus, a user can post a message with similar steps as previously discussed in prior paragraphs-of this invention. Nevertheless, unlike with group meeting messaging model, after obtaining and parsing information of the messages from each user, the console support software 6 of the control system 2 will deposit the message to both targeted user and the original sending user's message areas 21 of the private work space 16. Further, with same said steps of displaying messages in each user's browser as described in previous paragraphs, each user can view both own message and messages from peer user in section-2 of the browser 9.

For example, as shown in FIG. 7A, the user X input a message of “msg4 of user X” 30 and type “user Y” in input field of “To who”, and then submit the message by clicking on “Send” button. Similar as shown in FIG. 7B, the user Y input a message of “Msg3 of user Y” 31, and type “user X” in input field of “To who”, and then submit the message. Upon the refreshing the web-page in the web-browser 9 of each of the users, the user X will see the message 30 he/she sent and the message 31 from the user Y. Also the user Y will see both messages 30 and 31 at same time.

Again, the design choice of three sections of the web-page display and the order of each section is just a preferred example of implementation for non-group based peer user communication. This invention is not limited by web-screen display layout, for example, a screen display only with said section-1 and section-2 are also possible and so on without limitation.

The WCUWE of the CCDSVM has provided a security hierarchy for members of a team to work together cross multiple locations. With said security hierarchy and said steps of posting or un-posting file and folder, the console support software 6 of the control system 2 can specially let only a team leader with capability of posting folder or file to be viewed, shared, and accessed by all team members or by an individual member in a non-group meeting based environment. In addition, the console support software 6 also let each team member to post or un-post his/her file or folders to only a specific peer user one a time in non-group-meeting based environment. Again, the said files or folders could be on said control system 2 or on a provisioned system 3.

It is relatively straightforward for the WCUWE of the CCDSVM, more specifically the console support software 6, to support massive online users, who do not have account with the CCDSVM and can not login the CCDSVM, yet to view the dynamically posted files, folders, or messages posted by users with account of the CCDSVM.

In a preferred example, such as shown in FIG. 6E, the console support software 6 of the control system 2 provides a web-page to massive online users, who do not have to login the CCDSVM. The web-page could be layout with two major sections with section-1 to display messages in the sharable message area 18 in a designated user group's common work space 15 while the section-2 to display file or folders in the sharable file or folder area 19 in said designated user group's common work space 15.

Meanwhile, for users belong to same said designated user group, each user from a web-browser on a computing system across said network login to the CCDSVM and get said group online meeting web-page as shown in FIG. 6A for the user X and in FIG. 6B for the user Y. Further as described previous paragraph, each user in said group can instantly post message to said message area 18 of the designated user group's common work space 15, or post a file or folder to the sharable file and folder area 19 in the designated user group's common work space 15. Also, each user in the user group can instantly un-post the previously posted files or folders by removing the corresponding file or folder entry in the file and folder area 19 of the designated user-group's common work space 15, or un-post the previously posted messages by removing them from the common message area 18 of the common work space 15 of the user-group as described in previous several paragraph-.

Meanwhile as previously described and as shown in FIG. 6E, said web-page in the browser 9 is for access by massive online users, who have no account with the CCDSVM. The web page can be dynamically updated, displayed, and further be viewed by the massive users anywhere through their own browser 9 accordingly with the same pace as dynamically display of said section-2 and section-3 of a web-page in the browser 9 as shown in FIG. 6A and FIG. 6B. Again, the two sections of a web-page display layout is a preferred example and it does not limit this invention because with this invention other layout is also possible, for example, it may be desired to have web-page layout only contains one section, which is either for messages or file or folder's display depending on the application's need.

As shown in FIG. 8A, FIG. 8B, and FIG. 8C, with non-group based peer-to-peer post or un-post files and folders, people may often do not remember how many files and folders have been posted for sharing. For example, as shown in FIG. 8A, the user X can select “folder 2” 32, select a post on operation menu, and provide target “user Y” to share “folder 2” 32. As show in FIG. 8C, the user Y can see “Folder 2” 32 of the user X in the web-browser 9 of the user Y after the user X post “Folder 2” 32. If the user X selects various files or folders for sharing with other dozen people, the user X will have difficult time to remember what has been shared and who are targeted users shared with. As shown in FIG. 11, the console support software 6 of the control system 2 can provide each user, such as user X for example, a sharing control list for displaying of how many files or folders being posted by him or her and shared to whom.

As shown in FIG. 11 of the personal t sharing control list in the user X's web-browser 9, an entry of posted “Folder 2” 32 is listed at bottom of the sharing control list and it is posted/shared to/with the user Y. Further, said console support software 6 can provide each user to selectively un-post the previously posted file and/or folder by clicking on a “delete shared?” option of an operation menu over the corresponding entry for the posted file or folder in the sharing control list to generate an un-post operation task. For example, the user X clicks on “delete share?” to un-post the “Folder 2” 32. Thereafter, as described before said console support software 6 of the control system 2 will execute the un-post task. Further upon refreshing the targeted user Y's web-page in said web-browser 9, instead of seeing “Folder 2” 32 as shown in FIG. 8C, the user Y will see an updated view of said web-page as shown in FIG. 8B, where the “Folder 2” 32 has been removed. The operation menu for “delete share?” depicted here just for example and it could be displayed in other form.

In addition to let original user in a group to control the un-posting file or folder in a group based communication, the console support software 6 of the control system 2 may also provide a privileged user to un-post the previously posted files or folders in the displayed file and folder section-3 of said web-page. To support this capability, the console support software 6 will provide an operation menu to associate with said displayed files and folders in said display section-3, further to allow privileged user to perform similar un-post operation. After receiving the un-post operation, the console support software 6 will perform similar searching for selected file or folder in the group file and folder area 19 of the group common work space 15 of said group, if there is match, the corresponding entry will be deleted. Also, the file and folder section of the web-page in the web-browser 9 can be refreshed accordingly as described before.
